6 Claims.

This invention relates to a mounting for a spindle or the like, a plurality of which units are to be driven from a single belt traveling about the machine; and has for one of its objects to I resiliently urge the whorl against the belt.

Another object of the invention is to provide particularly pointedout in the appended claims.

In the accompanying drawing:

Fig. 1 is a sectionalview of the spindle mounting secured to the framework of the machine and illustrating in section the belt for driving the same;

Fig. 2 is a section on line 2-2 of Fig. 1;

Fig. 3 is a sectional view taken onsubstantially line 33 of Fig. 1;

Fig. 4 is a f-ragmental, sectional view on line 44 of Fig. 1;

Fig. 5 is a sectional view looking on substantially line 55 of Fig. 3.

In spinning or twisting machines in which a single traveling belt is utilized for driving a plurality of spindles, the spindle is resiliently urged to cause its whorl to contact with the traveling 35 belt for actuation of the blade; and in order that the moving parts may be well lubricated, I have arranged to provide a cup or casing for containing a lubricant and have mounted the moving part holding the spindle in this lubricant and provided a resilient element which urges the moving part with the spindle resiliently into engagement with the belt .to actuate the whorl on the blade; and in some instances, when it is necessary to hold the spindle out of contact with the belt, a catch may be utilized for this purpose; and the following is a more detailed description of the present embodiment of this invention, illustrating the preferred means by which these advantageous results may be accomplished:

With reference to the drawing, l0 designates the frame of a spinning or twisting machine, and II, the belt which travels the length of the machine for operating a plurality of spindles; the body of the mounting is designated l2 and consists of a cup-shaped casing having a hollow interior l3. A bolt l4 will serve to bind the frame between the jaw l5 and the casing l2 to hold the body, securely mounting it in position. An adjustment with reference to the frame may be had by the set screw i6.

Within this hollow l3 of the casing I have centrally pivoted a member I! having circular portions 18 and I9 adjacent its upper and lower ends to fit and having a bearing in the cylindrical interior of the casing l2. This member has a 10 conical support 20 in step 2| in the bottom wall of the casing. 'The member is reduced between these circular end portions and is provided with a bore 22 located eccentrically with reference to the center axis of this member II. In this bore 22 I have mounted a spindle, designated generally 23, which has a base 24 engaging the upper surface of the member II.

This spindle is of any conventional form provided with a blade 25, a whorl thereon 26, and a step 21 to prevent lifting of the whorl. A spring 28 serves to resiliently mount this spindle casing in position on the member l'l. Extending outwardly from the recessed portion 29 of the member l'l there is an abutment fin 30 against which a plunger 3| acts. This plunger is guided in a bore 32 formed through the wall of the casing and into the extension 33 from the casing. A spring 34 serves to force the plunger inwardly against the abutment 30. This spring may be adjusted as to tension by the threaded plug 35 held in position by the check-nut 36.

'The upper cylindrical portion |8.of the member IT is notched as at 31 and a latch 38 which is forced inwardly by spring 39 and retractable 35 by handle 40 will engage this notch .to prevent rotation of the member l1 by action of the spring 39. This notch is so located that in normal operation the latch will not engage the same, the engagement occurring only when the member I! is 40 rotated through a substantial arc.

In use, the bracket is mounted upon the frame Ill and the bracket will be so positioned that when the parts are in substantially the relationship shown in Fig. 3, the whorl will engage the belt II with substantially the desired amount of pressure, it being understood that the spring 34 tends to rotate the member I] and the spindle carried thereby into engagement with the belt by reason of the action of the spring 34. This spring will allow any irregularities in the belt, such as a connection at the ends, to swing the spindle against the action of the spring while causing the spindle to always follow the belt and engage the same with suilicient tension to obtain the desired traction necessary for driving the spindle.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible,

I claim:

1. A spindle mounting comprising a cup-shaped body to be fixed to a portion of the frame, a member in said body mounted to move about a central axis, means for eccentrically mounting a spindle on said memben resilient means for-urging movement of said member tovary the position of the spindle with reference to said body.-

2. A spindle mounting comprising a cup-shaped 1 body to be fixed to a portion of the frame, a member in said body mounted to move about a central axis,- means for eccentrically mounting a spindle on said member, resilient means for urging movement of said member to vary the position of the spindle with reference to said body,

opening therein, a member mounted in said opening to move about an axis centrallydisposed with respect to the member, means'for eccentrically mounting a spindle on said member, and means tending to cause movement of said member about said axis to vary the positionof said spindle with reference to said body portion. 1

5. A spindle mounting comprising a body to be fixed to a portion of the frame and having an opening therein, a member mounted in said opening to move about an axis centrally disposed with respect to the member and providedwith an abutment thereon, means for 'eccentrically mounting a spindle on said member, resilient means tending to cause movement of said member to vary the position of said spindle with reference to said body portion, and a spring moved latch on said body engageable by said abutment to limit th movement of said support.

6. A spindle mounting comprising a body to be fixed to a portion of the frame, a member having an opening therein, means for mounting said member to rotate about a central axis with refer-' ence to said body, means for eccentrically mounting a spindle on said member, resilient means for urging movement of said member to vary the position of the spindle with reference to said body, and a spring-urged latch positioned on said body and having a portion arranged to enter into said opening upon a predetermined movement of said member to lock the same against action by said resilient means.
